Homebrew Question Is the new Incognito that is built into Tinfoil safe?

MichaelShawJr · Feb 15, 2020

So the new Tinfoil has Incognito built right in. I used it on my new Emunand to install Incognito, but when I looked in the SD card to delete prodinfo.bin it wasn't there. The thing is, when wiping my serial number, it asked for a password. This password is needed to restore the prodinfo.bin, which tells me it could be encrypted. Anyway, I just want to make sure it's safe. I know it should be fine for protecting from a ban, but will it protect me from Homebrew applications that record such data? Should I run Incognito RCM to permanently delete it just in case? I already have a prodinfo.bin backed up on my pc anyway, plus this Emunand has NSPs so it will never touch Nintendo Servers, I have a clean Sysnand for that. I just don't want my prodinfo.bin stolen so I don't get my Sysnand banned. Thanks!

If you're this paranoid, you should not be running CFW in my opinion.

It asks for a password because it stores the encrypted backup in your nand so you can’t lose it.

nothing can read the backup without your password.

Hey Blawar,

I was just wondering on what location within nand the prodinfo is stored?

Cheers.

Well since this thread is hot, I will ask. It is safe to update FW with prodinfo erased? Has it ever happened that Nintendo changes the prodinfo with an update? So Do I need to make a backup every time I Update FW?

I updated from 9.1.0 to 9.2.0 without problems.

Also updated with choidujournx multiple times, no problem

Hello, it stores the backup, encrypted with the user supplied password, in an unused section of the cal0 partition.

dump either your encrypted prodinfo with bis keys, or just decrypted prodinfo, and I will make a quick script for extracitng your backed up cal0 providing you remember the password you used for encrypting it.

It should be right on the main menu when Tinfoil boots on the latest version.
